How awful.

P. Diddy's ex and the mother of his children Kim Porter was found dead at her home in LA this morning, multiple outlets confirm.

The 47-year-old model's cause of death is not yet known, but she was reportedly suffering from pneumonia these last couple of weeks, and paramedics responded to a call for a "patient in cardiac arrest." She allegedly contacted her doctor just yesterday, complaining that she wasn't feeling well.

The rapper and Porter began dating in the mid 1990s and went on to have three children before splitting for good in 2007. She was mother to twins Jessie James and D'Lila and son Christian, and she also had son Quincy from a prior relationship.

"Sadly, I can confirm the passing of Kim Porter. I ask that you give the families privacy at this time," Diddy's rep said in a statement.

What tragic news. Our thoughts are with Puff and his kids.
